A Fast Algorithm for Locating the Object Point in Binocular Stereovision

After analyzing the principle and the shortage of the least square method and the normalized least square method used to get the object point position in binocular stereovision, a simple computation formula and the corresponding fast algorithm of the common perpendicular midpoint method is proposed. The result of the simulation experiments show that comparing with the least square method and the normalized least square method, the proposed fast algorithm not only is of simple computation, but also has the better anti-noise performance.
